TENTERING -M ACHINE.

SPECIFICATION forming part of Letters Patent No. 650,202, dated May 22,1900. Application filed December S0, 1899. Serial No. 742,143. (Nomodel.)

To all whom, it may concern:

Beit known that we,RoBE Er E. SMITH, WIL- LIAM E. BAKER, and JACOB JOHNGLAEsER,of Philadelphia, Pennsylvania, have invented an Improvement inTentering-Machines, of which the following is a specification.

Our invention has reference to centeringmachines; and it consists ofcertain improvements set out in the following specification and'shown inthe accompanying drawings, which form a part thereof.

This application has specialrreference to tentering-machines fortreating textile fabrics, and comprehends more particularly certaindevices for imparting a reciprocating motion to the longitudinal framesupon which clamps are carried and which hold the fabric. 7

The object of our invention is to provide suitable power devices whichshall be-simple in construction and capable of properly re-' ciprocatingthe said longitudinal frames carrying the cloth-clamps and at the sametime have capacity for adjustment while inmotion for the purpose ofvarying the extent of the reciprocations.

Our invention is applicable to any of the usual types oftentering-machines, and, more specifically considered, the power devicescomprise a reciprocating box structure in which the end of theoscillating shaft of the tentering-machine is journaled, said box beingconnected with the free end of a pivoted slotted arm, which isoscillated by a crank and sliding box or bearing working'in the slot ofthe arm. Furthermore, the fulcrum: point of the pivoted arm isadjustable to and from the crank-shaft, whereby the throw of the arm maybe increased or diminished and such adjustment as is necessary beaccomplished While the arm is in motion.

Our improvements will be better understood by reference to theaccompanying drawings, in which-- I Figure 1 is a sectional elevation atone end of the tentering-machine. Fig. 2 is a side elevation of thedriven end of the tenteringmachine. Fig. 3 is a cross-section of Fig. 2

on the line 3 3, and Fig. 4 is a perspective view of the adjustablebearingin the sliding box. i

A A are the two longitudinal frames of the tentering-machine and supportthe endless traveling chains B, having the clamps b,which grasp theselvage edges 'of the fabric 0. These chains are driven by means ofsprocketwheels in the ordinary manner, which reiceive their motion fromthe upright shafts of the bevel-gears D, said shafts being journaled inboxes E, sliding upon a transverse oscillating pivoted shaft F, to whichmotion is imparted for reciprocating the frames A. The shaft F isprovided with bevel-gears G, meshing with the gears D, so that therotation of the shaft F in this manner transmits power to the endlesschains B. The shaft F is journaled in'an upright frame H, pivoted at hto act as a fulcrum-point,- about which it oscillates and constituting avertical axis. The general construction of the tenteringmachine proper,and especially the manner of pivoting the'frame H upon its base h, isfully shown in Letters Patent to Gadd, No. 606,780, dated July 5, 1898.The shaft F is provided with a spur-gear I, with which a pinion Imeshes. Pinion I is secured to the drivingshaft J, and the teeth betweenthe gears I and I are sufiiciently loose to permit the oscillations ofthe gear I upon the pinion I. The shaft J is journaled in suitable fixedbearings and is rotated by a band-wheel J. So much of the structure asis above described is similar to constructions of -tentering-machinesalready well known and in public use. One end of the shaft F projectsinto a bearing M, the same being cylindrical in plan and journaledwithin a sliding box L and capable of rotating on a vertical axis. Thebearing M is set in an upright cylindrical recess within the box L andis heldin place by the upper bar of the slotted guide K, as shown inFig. 3. The sides of the box L are perforated to permit the entrance ofthe shaft F to connect with the hearing within said box. The box L isadapted to slidein 'a horizontal slotted guide K and is reciprocatedtherein by means of a link M, connecting with the upper or free end of apivoted arm N. The

lower end of this arm is journaled at N to an adjustable support R,adapted'to be raise'd' or loweredin a suitable guideway'r by means of ascrew-shaft, which may be adjusted by means of a worm and worm-wheelgearing'T or any other suitable means. The arm N is provided; withv alongitudinal slotted guide.- wayz'ng-inrwhich; a box" Oslid-es: Thecrank pin of a crank P is journaled inthe-box--0-. The crank is securedto the crank-shaft p, which is driven from the shaft J by means ofgearingQ Q. a 1" It will be observed that the rotation of the crankcauses the arm N to oscillate upon its pivot N,'and therebyreciprocate:the boxcl'lij;

in its horizontal guide K, .This,im.parts an oscillating motion to theshaft F about its vertical axis of oscillation it. ,By adjusting thesupport R vertically the pivot-point'N -j is brought nearer or fartherfrom the crank shafitand thereby changes the extent-of throw=oritravelof the free end of'thearmN. This: likewiseflchanges the extent ofoscillationof the sliaft F; and consequently enables, the extent ofreciprocation of thefra-mes-A to he=varied for securing the propertreatment to the fabric. Itwill be observed that by-our improvedconstruction thead'justment ofi the" extent of reciprocation may beperformed while the machine is in motion and whom the properobservations of the results can'b'e had.

While weprefer the constructionshownas beiifg excellently adapted to-thepurpose, we do=not confine ou rselves to the minor'det'ails; as these;-may be varied without departing from the principles of our invention;
